Domain Match

• Managed full time employees, interns and contractors
• Acted as "scrum master" for our agile development team
• Actively participated in design, architecture and code reviews, and had "final say" on architecture and code changes to the front-end server
• Worked closely with Product/Project Management and Quality Assurance teams to coordinate development and release schedules
• Responsible for delivering a high quality build to QA every other week
• Launched an updated product every other week, achieving 100% on-time launches, and a record one production bug in 2006 and zero production bugs in 2007
• Responsible for 40-50 projects per year including developing new small and large features, researching technologies for future projects, improving performance, requesting new hardware and generating reports to evaluate our product quality
• Promoted a culture of excellence in development, including design and code reviews, documentation and unit tests; when code is handed to QA, it is expected to be bug-free
• Helped grow the team to twenty developers

Domain Match

• Developed new tokenizing and matching algorithms to significantly improve the relevance of results returned.
• Significantly improved the performance of the product in terms of CPU load, response time and sustainable queries per second.
• Mentored summer interns.
• Served as team lead in the absence of our regular lead.
• Interviewed candidates for Domain Match, Sponsored Search and Content Match, and helped improve the interviewing process
• Helped develop consistent coding style guidelines used by both DM and SS
• Helped grow the team from two developers to seven

SharePoint Team Services version 2

• Developed the STS migration tool, \texttt{smigrate.exe}, which migrates sites from STS v1 to STS v2, or between two different STS v2 sites.
• Designed the FWP file format, which is a CAB file with an XML manifest describing the contents of the site.
• Designed and developed many of the core classes used by smigrate, FrontPage Solution Packages, STS Web Templates for creation and deployment including a CAB file reader and writer and XML manifest parser
• Designed the algorithm used for backing up sites, and for deploying them

SharePoint Team Services version 1 / FrontPage 2002 Server Extensions

• Developed FPSE/STS's handling of Thicket and MHTML files, including parsing, copying, moving, renaming and link fixup.
• Maintained the Unix build of FrontPage Server Extensions, including
• Fixing Unix-only build breaks
• Maintaining the Unix build machine
• Coordinating drops of the FrontPage Server Extensions source code to Ready-To-Run Software
• Integrating patches from Ready-To-Run Software, to ensure that FrontPage Server Extensions continues to build and run on all supported flavors of Unix
• Coordinated with the Windows team to deliver drops of FrontPage 2002 Server Extension, and to ensure that FPSE continues to install and run on the latest build of Windows
• Maintained FrontPage's component in Windows' Object Component Manager (OCM) which allows FrontPage Server Extensions to be installed via the Windows "Add/Remove Windows Components" menu

FrontPage 2000

• Developed and maintained portions of FrontPage's Microsoft Management Console (MMC) component, used to configure and manage FrontPage Server Extensions.
• Coordinated with the Windows team to deliver drops of FrontPage Server Extensions 2000, and to ensure that FPSE continues to install and run on the latest build of Windows
• Developed and maintained FrontPage's component in Windows' Object Component Manager (OCM) which allows FrontPage Server Extensions to be installed via the Windows "Add/Remove Windows Components" menu

Windows NT GDI/OpenGL

• Wrote an interactive OpenGL profiler for developers
• Wrote a scripted version of the OpenGL profiler to be used in a configuration tool

Microsoft Project

• Wrote utility for developers to find memory leaks in MS Project
• Coded and tested the MS Project '98 viewbar, a portion of the user interface

• Mentored students at multiple high schools, and on multiple teams to design and build a 5-foot-tall, 120 lbs robot in 6 weeks to play that year's game. Robots must operate both autonomously and under remote control. Game challenges have included:
• collect soccer balls and placing them into mobile goals
• collect and stack plastic bins
• collect large rubber balls, climb stairs and hang from a 10' bar
• manipulate PVC tetrahedrons
• shoot Poof balls into a 10' high goal
• collect and hang innertubes on a central rack.
• Taught students to use industry-standard tools such as CVS, Subversion and make.
• Used a PIC embedded microcontroller to implement control system, including PID loops, inertial motion tracking using gyroscopes and dual axis accelerometers, and dead reckoning based on optical encoders; taught students about each of these techniques.
